Recovery Act Investments in Obesity

Public Health Burden

The increasing prevalence of overweight and obesity, especially among racial and ethnic minorities, is a serious public health concern. Today more than two-thirds of U.S. adults are overweight, and more than one-third are obese. The percentage of children and adolescents who have a high body-mass index (a measure of body weight in relation to height) has almost tripled during the past three decades and now stands at 16 percent. Excessive weight is associated with numerous adverse health outcomes, including heart disease and its risk factors (e.g., high cholesterol, high blood pressure, diabetes), sleep disorders, and lung diseases.


Achieving and Maintaining Weight Loss

Although many Americans indicate that they are trying to lose weight, most have trouble doing so, and many adults who are successful at shedding excess pounds eventually regain them. Recovery Act-funded grants that are exploring potential new approaches for achieving and maintaining weight control and thereby improving health include studies to:

Prevention

Because reversing weight gain is problematic and often unsuccessful, prevention of overweight is critical. Recovery Act-supported research on prevention in various age groups includes studies to:

Basic Research

Understanding how fat cells and circulating fatty acids function may lead to more choices for weight loss and cardiovascular disease risk reduction. Recovery Act funds are supporting projects to:

  • Investigate how fat cells communicate with cells of the immune system to cause high blood pressure and atherosclerosis , and how physical activity disrupts this unhealthy communication.11
  • Use genetically modified mice to understand how fatty acids provide energy to muscles of the heart and why an excess of fatty acids can sometimes lead to heart failure in patients with diabetes and obesity.12
  • Improve understanding of why some people with obesity develop risk factors for heart disease, while others do not, by examining the contribution of genes that regulate proteins secreted by fat tissue. The results will provide new direction for development of therapies to prevent or reverse early vascular injury.13
